[TabRoom] Small but important release

===CHANGES RELEASED 12.1.08====
12.1.08
Fixed (at last) the Huge Housing Bug, which deleted all housing
requests for all the other students in a competitor's event when you
dropped a competitor from the tournament. This proved to be a
simple bug in the end; the trouble was that people kept reporting it
to me as "housing went away when i was moving housing around" when
it actually happens when you dropped a kid from the tournament
overall, not just their housing request. Ah well.
Now onto figuring out the Great Kentucky Round Massacre of 11/22.
Also fixed a couple of minor housing errors.
Added a drop shadow effect to make it less likely for you to click
on the wrong button.
11.27.08
Made some visual tweaks to the housing interface.
Made a way for a tournament director to remove a housing request
directly from the housing master list.
